Alcohol consumption and mental health conditions: Insights from a South Australian population survey to inform policy and practice

Abstract

ObjectiveAmong individuals with a mental health condition co‐occurring alcohol use disorders are common, but less is known about alcohol consumption in excess of recommended drinking guidelines. This study investigated the prevalence of lifetime risky drinking (>2 drinks daily) and single occasion risky drinking (>4 drinks on one occasion) among individuals with mental health conditions of different severities. MethodsData from representative cross‐sectional population surveys among South Australians aged ≥15 years (n=11,761) were utilised. Logistic regression models assessed associations between risky alcohol consumption, presence of a mental health condition and demographic characteristics. ResultsPrevalence of lifetime risky drinking was greater among both males and females with a mental health condition (p>0.001). Single occasion risky drinking was more prevalent among males with a severe mental health condition (p=0.01). Adjusted logistic regressions showed that only females with a mental health condition had greater odds of exceeding lifetime risky drinking levels (OR=1.39, CI 1.11 to1.75). ConclusionsThere are sex‐specific relationships between risky alcohol consumption and mental health conditions. Implications for public healthRisky alcohol consumption, in excess of guidelines, is of concern among those with a mental health condition and requires attention at an individual and population level.
